hello
I hope someone may be able to help or point me in the right direction.
I have some tubular chromed chairs with leather back and seats. They've
been up in the loft a few years and after cleaning them up am trying to
reassemble them.
The tubes are joined together with 2 inch self tapping (at least they
look like they're self tappers)screws and a spacing sleeve.

Two of these chairs have one of the four holes that take these screws,
blocked with a piece of broken screw. Now I know that I would drill
these bits out but, not being a consummate DIYer, I thought I'd ask this
group, the best way of doing this and if there are any gadgets around
that would make this easier/safer. I obviously want to avoid damaging
the thread that's been cut in the tubes by the previously unbroken screws.

If there's room for them to fall through the other side of whatever
they're screwed into then carefully attacking them with a drill might
persuade them to do that. Otherwise self-tappers are very hard and
won't really drill - the drill will probably slip and chew up the
chair instead. If there's a bit of screw sticking out (or even if
it's just flush) I'd try placing a small nut on it and then MIG-
welding through the hole - hopefully you can then remove the screw
with a spanner.
